The tower garden has been going for a month now, and it's a jungle out there! Here's a photo of the three week point:
And the four week point:
In the last week, the cucumbers have started taking over. I always forget how big they get, and they really start to encroach on the other plants' space. Next year I will probably grow just one instead of two. I may have to rotate some of the growing spaces soon to make sure the broccoli and arugula can get some more sun during the day. Right now they're covered by the cucumbers, and they don't seem too happy about it.
The lettuce is growing strong and we've been harvesting every few days. Some of the plants are getting leggy and will probably bolt soon, but they've all been healthy and tasty so far.
